1557.make v2 txns standard

Make v2 transactions standard. This also corrects a rule about admitting large orphan transactions into the mempool, to account for v2-specific fields. ref #1557

07e6d5b025 Refactor GetTxid() into UpdateTxid() to match coding style of hash member variable. 
UpdateTxid() is called alongside UpdateHash() when a CTransaction is
deserialized or constructed.  GetTxid() now returns a const reference.

1e84d84d3a Rename GetHash() method to GetSerializeHash(). 
When pulling from upstream we are now forced to examine GetHash() usage
and replace with GetSerializeHash() if the caller wants a double SHA256
hash, or with GetTxid() if the caller wants a transaction id.

5884044ba9 Introduce vpour to CTransaction. 
Transactions of version 2 and above contain a `vpour` field which is a vector of `CPourTx`
objects that embody our protocol. We introduce serialization primitives for boost::array
(we intend for changing the amount of inputs and outputs in the circuit to be simple).

SIGHASH_* operations hash this field like any other for now.
